Wild. S211 Ep3 Leaving big pharma for Tulum

I just watched yesterday's episode. It involved an expert flipper (Joshua) who had purchased a home for $980,000 and was planning to invest $140,000 and list it for $1,360,000. Then he got Alison involved. Spoiler Alert - Alison convinced Joshua to increase his budget and give her 30% of the profit once the house sold. He ended up investing $218,500. Per Zillow, the house was listed for $1,599,777, went through nine price changes over two months before they got an offer, and finally sold for $1,400,000. That means it cost the flipper $78,500 to make an extra $40,000 (not counting the extra carrying costs because the house was originally over-priced and the 30% he had to give Alison). The final sales price was not disclosed in the episode. I wonder why.
